CommuteTime

Find out when the optimal time is to start your commute, taking into account traffic. Get reports emailed to you in the morning and in the afternoon.

Description

This is a simple, command-line Go program that generates graphs of possible commute times and emails them to you. Which graphs to generate and where to email them are configured with environment variables in commute.sh. This is called by towork.sh or fromwork.sh. Cron should be configured to call these in the morning or the night. Make these scripts executable with chmod +x <scriptname>.

Costs

Be aware that the price of the Google Distance Matrix API calls used to generate the graphs are high. Each call costs 1 cent, meaning that to generate a 6 hour graph with 15 minute resolution and best, worst and likely outcomes will cost around 72 cents (6 * 4 * 3).

Alternatives

If you don't want to set up a whole Go environment on the system where this cron job will run (i.e. Raspberry Pi), here's another way.

1. Change commute.sh by removing the go build line.
2. Cross-compile for the target machine on another machine. For Raspberry Pi, run env GOOS=linux GOARCH=arm GOARM=5 go build .
3. Scp this executable and the scripts to the target machine. You should be able to run the scripts there and everything should work.

• You should use Cronhub for monitoring your cron jobs.
